Glenn, When I tested the switch, I was using each terminal and a chassis ground to check, but you are right, I need to check the switch by itself. Another reason why I am suspicious about the switch is because I have converted to 12 volts and that could have pushed the old switch (probably original) over the edge. I haven't installed my gauges yet (after market) so no information there. I have a new wiring harness, new battery and no other apparent problems. I do have a separate fuse panel connected by a lead from the switch accessory terminal for wipers, heater, etc. It only has power when the switch is off which matches what I found when I tested the switch leads.
